Stability Problems

[mnet674]

I'm getting to my wits end with some new components purchased...

DFI Lanparty UT Nforce 4 Ultra-D
3800+/4000+ a64
2GB GSkill/1GB OCZ
520W OCZ powerstream psu
x1800xt 256mb

I just cannot get the system to run stably in games, while it runs for hours in windows without even a hitch, as soon as a game is started it either hardlocks or BSODs within minutes. On the other hand it will run tests such as 3dmark and rthdribl flawlessly for hours without a crash too, and after testing even games as old as half-life the thing still locked up.

Anyone got any suggestions of further things I can do to find the problem hardware?

Edit: I'm getting a PCI gfx card tonight to test with

do you have 2gb of gskill & 1 gb of OCZ installed at the same time???

I would remove the 1gb of OCZ and try everything again - just run it with the 2gb of gskill in.

Good suggestion, but I already tried 1 pair, the other pair, both at once, mixing them together etc.
